The 40 Gbps LM4 transceiver QSFP +, supports Wavelength range from 850nm to 1310nm? By F***a on 03/07/2019
Hello, thanks for your question. Regarding to your question about Product ID #36442. Confirmed that it would support the wavelength of 1310nm and would be able to run that wavelength 160m @ OM4 and would be able to run that 2km @ OS2 fiber. The wavelength would be 1310 during both multi mode and single mode use applications. By M***g on 03/08/2019
